FOOT PRESSURE-DISTRIBUTER FOR TWO-ROW CULTIVATORS.

Specification of Letters Patent.

Patented oct. i5, raie.

I Application led January 4, 1918. Serial 170.210,38?. l

To all whom 'it may concern.'

Be it known that I, GEORGE D. HOUSTON, a citizen of the United States,residing at Rushville, in the county of Schuyler and State ofIllinois,`have invented certain new and useful Improvements in FootPressure- Distributers for Two-Row Cultivators, as set forth in theannexed specification.

This invention relates to a pressure distributer and equalizer for tworow cultivators.

Heretofore the beams of two row cultivatorsl have 'been stabilized bymeans of springs or by pressure exerted by the feet of the operator onthe two inner beams, and by his hands through suitable hand-holds on thetwo outer beams.

I t is the object of my invention to provide means whereby all four,beams may be controlled by foot pressure alone thus releasing theoperator from the necessity of exerting pressure manually on any of thebeams, making the work easier and the results more uniform.

A further objectv of my inventionis the provision of a pressuredistributer and equalizer' for two row cultivators, whereby pressureexerted by the feet is equally distributed to the four beams.

Further objects and advantages of my invention reside in the variouscombinations hereinafter described, as will be apparent as it is betterunderstood by reference to the following specification, when read inconnection with the accompan ing drawing illustrating the preferred emodiment thereof, in which- Figure 1 is a view in perspective of acultivator embodying my invention.

Fig. 2 is a detail in perspective of the pivotal connection of the seatbeam to the cross beam.

Referring to the drawing 5 indicates an axle, carrying wheels 6 andsupporting the frame 7 of the cultivator., The cult-ivator beams 8 arepivotally supported at their forward ends by pendulum rods 9 dependingfrom a cross bar 10, mounted on brackets 11 which are secured to theframe 7. The cultivatorbeams 8 are divided into pairs, each pair beingconnected at their forward ends to an arch 1Q. The arches 12 areconnected at their upper ends to a cross beam 13. A seat beam 1lcarrying a seat l5 is supported b v an inverted T bolt mounted on theframe 7, above the axle 5.

The seat end of each of the Vthe well. known form of beam 14 preferablymade of two channels` '1s supported so that it may swing in bothvertical and horizontal planes. The forward end of t-he seat beam 14 ispivotally connected to the cross beam 13. Thus the operator by swingingthe seat beam le from side to side may shift the cultivatorbeams`laterally.

A rod 17 is connected for pivotal movement in two planes, adjacent therearward cultivator beams 8, and is provided at vits upper end with ahandhold 18. Adjacent their upper ends the rods 17 are pivotallyconnected to arms 19 pivotally mounted on the frame 7, above the Vaxle5. Similar arms 20 are pivoted concentrically with the arms 19, theupper ends of the arms 19 and 20 being connected by chains 21 andsprings 22. Chains '23 and springs :211 connect the upper ends of thearms 20 to the brackets 11, and to a transverse member 25 connecting thebrackets 11.

eavy springs 26 are connected to the vrods 17 above their pivotal axesand to transverse rods 26 near the forward ends of the cultivator beams8. The latter construct/ion is spring lift, its purpose being to liftthe cultivator beams 8 to inoperative position when the rods 17 areswung forwardly by the operator. All of the foregoing construction iswell known in the art and forms no part of my 'present invention, beingdescribed merely to make the application of my invention clear.

The two inner cultivator beams 8 are each provided with a stirrup 9.7 inwhich the operator places his feet while seated on the seat 15. He maythus exert a downward pressure on the two inner cultivator beams tostabilize and maintain them constantly in the desirable working depth.In order that this pressure may be transmitted to the outercultivatorbeams I provide two U bars 28 pivotally mounted on the frame 7above the axle 5 in suitable bearings 29. The free ends of the U bars 28adjacent the seat beam 14 are connected by chains 30-to the rods 17adjacent their' lower ends. The other free ends of the U bars Q8 areconnected by chains 31 to the outer rods 17 adjacent their upper ends.'Thus when the inner cultivator beams 8 are depressed by the feet of theoperator in the stirrups 27 the ends` of the U harsy 28 are swungdownwardly and through the connecting chains 81 and rod 17 the eineroultivator beamsvS ari` similarly depressed.

x'lf'he or er tir is thereby enabled to control and st"n1 lize all'ifour beams by the pressure of his reet,` leaving his hands Jfree todrive the team and perform other necessary opera` tions in handling thecultivator. When it is necessary to litt the cultivator beams, the :teetare disengaged from the stirrups 27 and *he rods l? swung forwardly bymeans et the hand-holds to permit the spring litt to operate.

From the foregoing it will be readily understood that l have perfected asimple and useful device which makes the work of han dling thecnltivator much easier because the operator can stabilize the cultivatorbeams with less exertion through pressure applied by means 'of the feet.All of the beams being moreover subject to the same degree of pressure,the work is much more uniform than is possible where each ot the beamsis indeper, denti y controlled.

My invention involves a relatively slight addition to the constructionof two row cultivat-ors as now known, and provides manifest advantageswhich materially improve the operation of the cultivator.

T`v'arious changes may be made in the torni, arrangement andconstruction of the parts, without'departing from the spirit and scopeof the invention, or sacrificing any of its material advantages, theform hereinbefore described being merely the preferred embodimentthereof.

l claim:

l. ln a two row cultivator, the combination of two pairs of resilientlysupported cultivator beams, and means connecting the beams ot each pairwhereby they are maintained in conjointly movable relation underdownwardly directed forces, said connecting means being operative in onedirection only whereby the contiguous beams orn each pair are freelymovable upwardly independent oi1 the other beam ot each pair.

In a two row cultivator the combination of a frame, two pairs ofcultivator remesa beams supported thereon, U bars pivotally mounted onsaid trame, and means connecting the free ends of said U bars to saidbeams whereby downward pressure exerted by the operator on one of eachpair of beams is transmitted to the other beams.

3. ln a two row cultivator the combination of a frame, a plurality ofcultivator beams supported tor vertical movement on said frame, acentrally disposed seat beam, a seat thereon, stirrups on the cultivatorbeams adjacent said seat beam to receive the feet ot the operator andconnections between the cultivator beams bearing said stirrups and theremaining cultivator beams whereby downward pressure exerted by theoperator. is applied uniformly to all of the beams.

el. ln a two row cultivator the combination of a frame, two pairs ofcultivat-or beams supported for vertical movement thereon, a centrallydisposed seat beam, a seat thereon, means on one of each pair of saidcultivator beams to receive the feet of the operator and connectionsbetween each pair of beams whereby downward pressure exerted by theoperator is applied uniformly to the other beam of each pairt 5. ln atwo row cultivator the combination of a trame, a plurality of cultivatorbeams mounted for vertical pivotal movement on said Jframe, asubstantially vertical rod pivotally connected to each of saidcultivator beams, a U bar pivoted on said frame., one arm of said U barbeing connected to the rod, carried by onev of said cultivator beams,adjacent its upper end, while the other arm is connected to the rod,carried by the adjacent eultivator beam, adjacent its lower end, wherebydownward pressure eX- erted on the latter eultivator beam is transmittedto the former.
